So you had good luck with the RE10? Just started running my newly rebuilt C6 USA. It has a bad air leak somewhere. Won't idle at all. Thanks to Chris Peralta for the carb settings. It won't come close to idling with the carb idle gap set properly. Won't stop racing. LSN has to be very rich and the idle gap very small then it just stalls. I'm going to put my FMS carb on it. Looking forward to racing it. Motor showing killer power even with air leak. I will be trying my RE10 also.

Had good luck with the RE10 on the k9.I've never ran a c6 so I don't know what pipe to run on it but heard they have killer power.

I'm interested in one but can't find anything on them.


I have not yet seen a cross10 run but I do have the Shark9 which is basically the same engine except the Shark9 has a balanced crank and the Cross10 does not have the balanced crank. My Shark is starting to run great and getting much better mileage as well, pitting at 8 minutes I only needed 80CC's to fill the tank so 10 minute stops should be no problem now that it's fully broken in.

My Shark 9 is really starting to come in nicely with 7.5- 8 minute stops running around 250 in my MBX6. The Shark makes wicked useable power and had no issues with short run-ups to big jumps and no issues with the lower speed rythem sections this past weekend at our first RCPro regional race in Alberta, Canada. I qualified and finished 3rd in expert buggy against some pretty stiff competiton.......not bad for an on-road guy:D
Look in the pic who tq ed and finished first:sneaky:

Nice...I told you that Shark was good :D

Yeah thanks Don, it took a while for it to break in and after I realised that I needed to run it a little hotter than I thought 240-260 it really makes wicked power and has decent runtime. It is also taking me a little time to get the whole clutch thing figured out.....one other thing that electric on-road does not have:smile:

Is there a turbo head button for the S9 and what plugs do these engines like the best? I run 30% OD and 2045/198 combo with a 6.5mm restrictor.

Thanks

01080 is the part number for the turbo button for an S9 engine. As for plugs I prefer the number 5 plug unless the temp is close to 100 then I will run a 6. These are RB plugs, they seem to last much longer other plugs I have tried in the RB's.

I need some new bearings in my WS9, where can i get a ceramic bearing that is 13 x 25,4 x 6 ?

Glo plug size/thread length
 
I’m sure I had read the RB S5 motors took a plug which have a longer thread than standard.
Is this correct ?

I took the one out of the motor to show the hobby shop and they said a OS A3 or A5 are the same type of plug,just need to choose what temp range is required.

As the motor was used it may have had the wrong plug installed,so I may have shown them the wrong sample plug.

The only standard OS plug that is the same is the LC3 Hot plug. OS plugs are short body plugs, they will work but you might be chasing the tune all day long. If you can't get RB or Novarossi plugs get an odonnell or a mccoy and you will be fine.

Thanks Chris.
I was unable to find any one local,in the end "A Main" had some which i have now ordered.

Hey Chris how did Nats go. The track looked fun as hell.

Hey man, nats were awesome! The heat and the altitude made it intresting for many people who have never raced at 6500 feet. For me I was just hoping to finish as close to mid pack as possible, I finished all my quals with no issues and made the 1/4 finals in truck and the 1/8 finals in car, both were better than mid pack so I was happy.

PIPE FOR KILLER 10
 
So Chris being in Colorado and I'm from Colorado, Denver area, and not finding the 2045 pipe setup in the budget, would you suggest the next best choice is the RE10? This is for the Killer 10. Is the 086 pipe a choice also? Or which of the 2 would you go with? Also what glow plug are you recommending? I'll be running 30% Byrons fuel. Any help greatly appreciated, Thanks.
